FIREPROOF SUPPORT FOR ELECTRICAL WIRES IN RAILWAY-CARS.

To all whom it may concern:

Be it known that I, EDWARD T. ROBINSON, a citizen of the United States of America, residing at the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Fireproof Supports for Electrical Wires in Railwayars, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this speciication.

My invention relates to supports for electrical wires arranged in railway cars and more particularly cars of street railways, and it has for its object to provide supports of this character of fire-proof nature in which the wires are disposed in a manner to prevent ignition of inflammable parts of a car in the event of the occurrence of a fire caused by short circuiting of an electrical current carried by the wires.

Figure Iis a cross section taken through my sup orting means and a part of the body of a rai way car. Fig. II is an elevationv of the parts shown in Fig. I. Fig. III is a longitudinal section taken through the support at the location of one of the lamp or switch brackets. Fig. IV is an elevation of one of the lamp or switch brackets. Fig. V is a cross section taken through the sup ort at one of the lamp or switch brackets. ig. VI

-is a similar view to Fig. I with a switch alplied to the bracket illustrated, instead of t amp shown in Fig. I.

A designates a part of the body of a railway car which constitutes that portion interior of the car at the inside angle of its up er deck. At the angle of this part A are moIding strips B, spaced apart from the angle sufficiently to provide a channel.

l designates fire roof conduit sections that may be of meta or any other suitable material and which occupy the channel between the angle of the part -A and the molding strips B. These conduit sections are provided at their ends with screw threads 2y and their ends are separated to furnish outlets from the conduit in the combined sections through which electrical conductors 3 laid in the conduit may be led, as seen in Figs. I and V. The molding strips B are discontinued adjacent to the outlet openings in the conduit, as seen most clearly in Figs. III and VI, thereby providing a gap between saidstrips Speccaton of Letters Patent.

Serial No. 415,355.

for the passage of the branches of the electrical conductors, in such a manner as to permit of such branches being outof contact with the molding strips. 4 are hollow brackets secured to the part A by suitable means, such as screws 4 at the locations of the outlet openings in the conduit, and which are rovided with apertures 5, through which the branches of the electrical conductors are led. These brackets are of fire-proof material, for instance metal, and they are provided with flanges 6, as illustrated in Fig. III, that overlap the molding strips B for the purpose of holding said molding strips in position against the conduit sections 1. The brackets are also provided at their ends with internal'screw threads that receive the external screw threads of the conduit sections for the purpose of uniting their parts. The brackets are designed to receive the bases of electric lamps as illustrated in Figs. I and V or the bases of switches, as seen in Fig. VI to which the branches of electric wires are connected in the usual manner.

I claim:

1. The combination with the inside angle part of the upper deck of a body of a railway car, of molding strips associated with said inside angle part, a fireeproof conduit located between said molding strips and said inside angle part of the car body and provided with outlet openings for the passage of electrical conductors, and fire-proof brackets secured to said inside angle part of the car body and overlapping the ends of said molding strips for the support thereof, substantially as set forth.

2. The combination with the inside angle part of the upper deck of a body of a railway car, of molding strips associated with said inside angle part, a fire-proof conduit located between said molding strips and said inside angle part of the car body and provided with outlet openings for the passage of electrical conductors and fire-proof brackets secured to said inside angle part of the car body and overlapping the ends of said molding strips for the support thereof said brackets being provided with apertures located contiguous to the outlet openings in said conduit, substantially as set forth.

3. The combination, with the inside angle part of the upper deck of a carl body; of molding strips associated with said inside angle part and spaced from each other, a lire l spaced apart and secured t0 the internally" proof hollow bracket recessed into the inside screw-threaded ends of the hollow bracket. angle part, and having internally screw-V threaded ends, an aperture, in the Wall thereil of, and v[langes Overlapping the molding" strips, and Vlire prooi conduit-sections having externally screw threaded adjacent ends EDVARD T.
